/**
 * @Description :认证中心
 * SpringSession核心原理
 *   1、@EnableRedisHttpSession  导入 RedisHttpSessionConfiguration  配置
 *      1、给容器中添加了一个组件
 * 		SessionRepository =》RedisOperationsSessionRepository =》redis操作session，session的增删改查
 * 	2、SessionRepositoryFilter => Filter:session 存储过滤器，每个请求过来都必须经过filter
 * 		1、创建的时候，就自动从容器中获取到了SessionRepository
 * 		2、原始的request，response都被包装。SessionRepositoryRequestWrapper,SessionRepositoryResponseWrapper
 * 		3、以后获取session，request.getSession()
 * 		4、wrapperRequest.getSession() ==》SessionRepository中获取到的
